When your son doesn’t pay attention and adds dishwashing liquid to the dishwasher instead of detergent — yes, you know what that means — here’s a tip:
After cleaning up as much bubble mess as you can (i.e. the floor, so you can get to the dishwasher), pour vinegar into the dishwasher. It helps break up the bubbles, and you get far less foaming.
I’m adding it to the list.
Well, I’d been meaning to run vinegar through the dishwasher anyway. Guess now was as good a time as any. Well, better, actually!
